Abstract

Methods and devices for determining the distance between a location emitting an acoustic, photonic, or electromagnetic waveform and a location detecting the emitted waveform are provided. In certain applications the emitting and/or sensing locations may be selected from within a human, mammalian, or animal body. The subject methods and devices find use in a variety of different applications, including cardiac resynchronization therapy. In certain aspects, a bioelectric signal pathway carries a pulse from cardiac pacing pulse generator to deliver a pacing pulse to a heart while protecting a bioelectric measurement device from interference from the pacing pulse.
